Paul Thurrott has revisited his Windows Phone review, specifically the part that covers the update process. Now we're all more than aware of how awful previous Windows Phone updates have been (just take a look at NoDo) for some consumers, depending on what carrier their with, but it seems as though this isn't set to change anytime soon. Carriers will be able to block updates as they see fit (unsure as for the motive to do so) and leave users high and dry without the latest version.
Thurrott previously explained that carriers could "veto" an update, which would then be automatically offered to consumers the next time a software update is released. It seems that Joe Belfiore (who provided Thurrott with said details) was incorrect, due to the fact that carriers appear to have the ability to block updates galore. As an example: both 7740 and 8107 still haven't been delivered to some consumers.
We have touched on this before, with a post on the Windows Team blog detailing that carriers could block any updates as they wished, but ultimately consumers should receive all updates pushed out by Microsoft. All in all, a real pain for consumers. Looks like we'll have to take matters back to the drawing board to plan future wars against the carriers. Are you still missing an update (or updates)? Let us know in the comments.
